2 l_start number := dbms_utility.get_cpu_time; 3 begin 4 for x in (select object_name from stage) 5 loop 6 insert into t (encrypted_name) 7 values ( encryption_wrapper.encrypt 8 (x.object_name, 9 "Secret Key Secret Key Secret Key")); 10 end loop; 11 dbms_output.put_line( (dbms_utility.get_cpu_time-l_start) || " hsecs" ); 12 end; 13 / 2502 hsecs PL/SQL procedure successfully completed. it takes 25.02 CPU seconds to generate and insert the data. Thus, it takes almost six times more CPU to perform the encryption as opposed to leaving the data unencrypted. Even if we bulk up the operation, using an INSERT AS SELECT statement, we ll see a large disparity: ops$tkyte%ORA11GR2> truncate table t; Table truncated. ops$tkyte%ORA11GR2> declare 2 l_start number := dbms_utility.get_cpu_time; 3 begin 4 insert into t (last_name) select object_name from stage; 5 dbms_output.put_line( (dbms_utility.get_cpu_time-l_start) || " hsecs" ); 6 end; 7 / 8 hsecs PL/SQL procedure successfully completed. ops$tkyte%ORA11GR2> truncate table t; Table truncated. ops$tkyte%ORA11GR2> declare 2 l_start number := dbms_utility.get_cpu_time; 3 begin 4 insert into t (encrypted_name) 5 select encryption_wrapper.encrypt 6 (object_name, 7 "Secret Key Secret Key Secret Key") 8 from stage; 9 dbms_output.put_line( (dbms_utility.get_cpu_time-l_start) || " hsecs" ); 10 end; 11 / 374 hsecs PL/SQL procedure successfully completed. Yes, 374 seconds versus 8 seconds is a more striking disparity, an almost 47 times increase in CPU utilization because of encryption when we performed the more efficient bulk operation. Clearly, this increased demand on CPU will have an impact on our modifications to the column. INSERTS, UPDATES, and MERGES will surely be affected, (but probably not DELETEs).

Splitting and Merging PDF Files in C# Using iTextSharp - CodeProject
9 Mar 2013 ... I recently posted about using PdfBox.net to manipulate Pdf documents in your C# application. This time, I take a quick look at iTextSharp, ...

We focused on filling out forms. Form fields can be organized hierarchically, which changes how forms are filled out. You learned to optimize the process using a field cache. We also looked at flattening a form partially and taking over the flattening process altogether. Then we looked at the other type of form. XFA forms are based on the XML Forms Architecture, and they come in two flavors: static XFA forms and dynamic XFA forms. Most of the static XFA forms can be filled with iText in the same way as AcroForms, using the same code. But when we inspected what an XFA form looks like on the inside, you discovered that there were exceptions. You created a dynamic XFA form using Adobe LiveCycle Designer, and you used iText to inject an XML data file into that form. Finally, you learned more about Reader-enabled forms. Filling such a form with iText can break the extra features that are added to the form, but you learned how to avoid this. This chapter concludes the second part of this book about manipulating existing PDF files. You had an overview of the different manipulation classes in chapter 6; you added links, bookmarks, and annotations to existing documents in chapter 7; and you ve learned almost everything about filling out interactive forms in this chapter. In the next chapter, you ll discover how to integrate the standalone examples we ve looked at so far in a Java servlet; for instance, how to integrate a PDF form in a web application.

At this point, the key requirements for the application have been gathered from the use cases. Based on these use cases, it is possible to create an object-oriented design. There are a variety of techniques used in object-oriented design (you may have heard of CRC cards and decomposition, in addition to others), and in this chapter, I ll use ideas from both decomposition and CRC cards. A form of decomposition will be used to identify the nouns in the use cases, and then narrow down which of these are actual business objects. These objects will be described in terms of their class, responsibility, and collaborators (CRC).
